SPECIFICATION forming part of Letters Patent No. 760,020, dated May 17, 1904.

Application iiled January 11, 1904. Serial No. 188,473. (No model.)

To all whom it may con/cern,.-

' Beit known that 1', WARREN A. SANDERS, a citizen of the United States, residing' at Hamilton, Butler county, Ohio, (post-office address No. 303 Ross street, Hamilton, Ohio,) have invented certain new and useful Improvements in Coating-Machines, of which the following' is a specification.

Thisk invention pertains to improvements in coating-machines designed particularly with reference tothe coating of' paper, and the improvements will be readily understood from the following description, taken in connection with the accompanying drawings, in which Figure 1 is a side elevation of' a machine embodying my improvements; Fig. 2, a vertical longitudinal section of the same; Fig. 3, a'diagrammatic plan of' the main parts of the coatingdevices and their driving mechanism; Fig. a, a side elevation of' one of' the reciprocating' brushes and its actuating mechanism; Fig. 5, a side view of' one of' the eecentrics; Fig. 6, a vertical transverse section of one of' the eccentrics; Fig. 7, a side view of one of the reciprocating brushes and its immediate accessories; Fig. 8, a vertical transverse section of' the same, and Fig'. 9 a view of the under side of one ofl the brush-ribs.

' In the drawings, 1 indicates fixed frame parts seated for the support of' the various moving and other lighter parts of' the machine, the frame consisting, generally speaking, of two side housings disposed parallel with each other; 2, the roll of' paper to be coated; 3, a first vat of coating material; 4, a first fountain-roll dipping thereinto; 5, a first coating-roll having preferably a brushsurf'ace, this coating-roll being disposed over and running in contact with fountain-roll l1;

6, a first drum disposed alongside of and par-.

face of the paper, the paper passing upwardly between rolls 1l and 12; 13, the paper after it has passed from the second coating apparatus and been subjected to the action oi rcciprocating brushes; 14, along' brush device, generally considered, longitudinally reciprocating in contact with the paper turning over drum 6 and distributing and otherwise improving the condition of the coating delivered thereon by the first coating-roll; 15, a similar brush device cooperating with the second drum 12 to deal with the coating material delivered by the second coating-roll 11, and 16 several pairs of long brush devices, three pairs being illustrated, each pair comprising two brushes, one reciprocating longitudinally over and the otherunder the paper after leaving brush 15, the two brushes of a pair being opposed to each other upon the paper passing between them.

The proper motion being given to the various rolls and brush devices, the paper becomes coated and the coating distributed and polished on both sides of the paper without the necessity for passing the paper through any bath of' coating material.

Proceedingwith the drawings, 17 indicates a pair of arms having their heels pivoted to the framing, these arms being disposed across under each end of second vat 9, which vat `has feet engaging claws on the arms, whereby the vat is removably supported in the arms; 18, adjusting-screws supported by the framing below these arms to serve in adjusting the` vat vertically with reference to its fountain-roll, the first vat being provided with a similar supporting' and adjusting dcvice; 19, the reciprocating' brush-carrier of one of the brush devices, this carrier-being in the form oi" along bar extending across the machine; y 20, a pair of guide-studs projecting outwardly from each end of the brush-carrier and sliding in guiding-eyes formed in appropriate portions 0i' the framing, whereby the brush carried by the brush-carrier may be reciprocated accurately with reference to the surface of the paper; 21, downwardly-open jaws carried by the brush-carrier, one pair of jaws near each end of the brush-carrier or near each end of the brush which it is to IOO sys

carry; 22, the back of the brush; 23, the bristles of the brush; 24, a block sliding vertically in each of Vthe two jaws of the brushcarrier; 25, a screw arranged vertically in the brush-carrier over each of these blocks, the

.thread of the screw engaging a nut carried by the brush-carrier, the screw having its lower end swiveled to the block and having its upper end provided with a hand-wheel, a second hand-wheel upon the screw forming a locknut to bind the screw to adjusted position; 26, a tapering dovetailed rib secured upon the back of the brush at each of the two blocks 24, its dovetailed portion engaging a tapering dovetailed recess in the lower face of the appropriate block 24; 27, a spindle journaled across each of blocks 24 over the kdovetailed rib and capable of turning and of moving endwise; 28, a latch projecting downwardly from the spindle and engaging a notch in one end of the appropriate dovetailed rib,-and 29 a spring upon the inner end of the latch-spindle tending to draw the spindle inwardly.

A description of the working of one of the brush devices will answer for all. The brushcarrier reciprocates in its guides and theI brush is delicately adjusted to and from it to produce the proper brushing pressure on the paper, this adjustment being accomplished by means of the screws 25. The brushes become united firmly to the brush-blocks 28 by the dovetailed arrangement, firmness being secured by the taper of the dovetailing. The springs urge the dovetailed ribs tightly into their recesses; but Vby pulling the latch-spindle endwise and turning their latches up out of engagement with the ribs the brushes can be readily removed from the blocks and from the machine. When the latchesare in action, the springs not only serve to draw the brushes firmly to place in the blocks, but serve to hold the latches seated in their notches.

Proceeding with the drawings and giving consideration to the mechanism forimparting motion to the various parts, 30 indicates a cam-shaft mounted alongside the machine; 3l, a bell-crank mounted on the framing over the cam-shaft, one bell-crank at the end of each brush device; 32, an eccentric mounted on the cam-shaft in the plane of each of the bellcranks; 33, the eccentric-rods extending from the eccentrics to the horizontal arms of the appropriate bell-cranks; 34, links connecting the vertical arms of the bell-cranks with the appropriate brush-carriers, the construction being manifestly such that the rotation of the cam shaft produces reciprocations of the brush-carriers and brushes; 35, a false hub secured to the cam-shaft alongside each of the eccentrics, the eccentrics themselves having open centers free of the cam-shaft; 36, bolts engaging the eccentrics and slots in wings of the false hubs, the construction permitting the eccentric to be shifted transverse to the cam-shaft, so as to adjust the stroke of the eccentric and of the brush operated by it; 37, Y

a separable face-half for the eccentric secured to the other half of .the eccentric by rivets, the periphery of the eccentric being very deeply grooved; 38, phosphor-bronze tire disposed in the bottom of the groove of the eccentric; 39, a series of antifriction-rolls disposed in the groove of the eccentric around this tire; 40, a phosphor-bronze bushing for the eccentric-strap encircling the series of antifriction-rolls, and 41 the eccentric-strap, divided and bolted as usual with eccentricstraps, its bore engaging the bushing 40.

The stroke of the eccentrics can be readily adjusted by the bolts of the false hubs, and the eccentric-rods are screwed into the straps, so as to permit their adjustment of length. The splitting of the eccentrics by providing them with separable front faces permits of the tires and bushings and antifriction-rollers and straps being gotten into the grooves of the eccentrics.

Proceeding with the drawings and giving consideration to the transmitting mechanism for driving the rotary parts, 42 indicates a driving-shaft bevel-geared to the cam-shaft; 43, a'pulley on the driving-shaft by which power is brought to it by belt; 44, a countershaft disposed across the machine; 45, a belt engaging pulleys on the driving-shaftand the counter-shaft; 46, gearing connecting the counter-shaft and the tirst drum 6, whereby motion derived from the driving-shaft becomes transmitted to that drum; 47, one cone of a speed-changer on a shaft disposed across the machine; 48, a sprocket-chain transmitting motion to this cone from the counter-shaft; 49, the second cone of the speed-changer; 50, the transmitting-belt of the speed-changer engaging both cones; 5l, a sprocket -V chain transmitting motion from the second cone of the speed-changer to each of the two fountainrolls; 52, a pulley on the shaft of the second drum, serving as a means by which motion may be -transmitted by belt from any suitable overhead shaft to the second coating appara- IOO IIO

tus; 53, gearing connecting the second drum drums and coating-rolls can be adjusted by means of the speed-changer.
